CityCoins vs Goldilocks: which fits your DeFi plans? (2026)

CityCoins and Goldilocks serve different ecosystems and different purposes. CityCoins is a set of city-specific cryptocurrencies on Stacks, starting with MiamiCoin (MIA). Its model centers on open mining, Bitcoin-denominated rewards and a stated aim to direct part of mining proceeds toward cities and communities. Goldilocks is Berachain-native DeFi infrastructure: its products include Goldiswap, an AMM designed around price floors, and Goldilend, an NFT lending platform. LOCKS is its governance token. The practical choice is therefore less about choosing between equivalent products and more about deciding which ecosystem and activity you want to engage with. CityCoins is the closer match for city-branded coins and mining; Goldilocks is the closer match for Berachain trading, lending and governance. Both have modest TVL, so neither should be treated as established based on size alone.

CityCoins focuses on mining city-specific coins through Stacks smart contracts. The project says participants can earn BTC from a CityCoin protocol as usage grows, while part of mining proceeds is intended to benefit city governments and communities. Those rewards and allocations should not be treated as guaranteed: the project does not quantify the protocol-level share, and city coins have no guaranteed utility beyond what the protocol and communities build. Goldilocks offers a different set of activities. Goldiswap is described as an AMM with price floors, and Goldilend offers NFT lending; Goldilocks describes its loans as interest-free and unliquidatable. These are project descriptions, not assurances about performance under stress. The design also includes LOCKS governance. Before using either project, make sure you understand what you are committing funds to and what conditions apply to rewards, swaps or loans.

Neither project publishes a fee schedule. For CityCoins, mining and transfers involve Stacks network transaction costs, which appear in the wallet before signing. Any protocol-level share of mining funds sent to cities or stackers is not quantified. Goldilocks has not published costs for Goldiswap swaps, Goldilend borrowing or origination, or any protocol cut. Its description of loans as interest-free does not establish that every part of using the product is cost-free. Berachain gas may also apply. Check current documentation and the transaction confirmation screen for the specific action you plan to take. If a fee or loan term is not clear before you commit, do not assume it is zero. Costs can also vary by the action and network conditions, but neither project publishes figures here to compare directly.

CityCoins has no audits listed, and its safety information does not mention a hack or incident. Its smart contracts still carry bug and design risks, and funds committed to mining may not be recoverable. Goldilocks has two audits listed, but the auditors and findings are not public. Those listings are not a guarantee of safety, particularly for mechanisms such as rising price floors and unliquidatable loans, whose performance under stress is not explained. Both projects also have limited on-chain footprint: CityCoins has about $1.4 million in TVL and Goldilocks about $528,000. Goldilocks additionally has thin LOCKS trading liquidity, which can make exiting a position difficult. CityCoins is tied to Stacks; Goldilocks is tied to the young Berachain ecosystem. Consider contract, liquidity and chain risks, and check the rules where you live before using either project.

Choose CityCoins if your main interest is city-specific crypto, Stacks mining and the possibility of Bitcoin rewards, and you accept unclear current product details, limited liquidity and the absence of listed audits. Its public API and documentation may also suit developers looking to work with CityCoins or Stacks data. Choose Goldilocks if you already want to use Berachain DeFi and value a suite that combines an AMM, NFT lending and LOCKS governance. Its two listed audits are a point of distinction, but their details are not public, and its low TVL, thin token liquidity and unusual lending mechanics remain important cautions. If you need published fees, clearer operational detail or deeper liquidity before participating, the information here does not establish either project as a good fit. Neither is a low-risk choice.
